Tweet interesting info about you., but don't just advertise. Personalize it a bit. It also doesn't hurt to retweet interesting stuff from other twitter users.
You can start following some one relevant to your industry, this is an effective way for increasing the following list on the Twitter.
Check my Signature you can check my Follow count on my twitter profile on my signature as well =) real proof.
Follow tons of other Twitter accounts, many will follow you back. Along with that, create other accounts and you're golden!
I have a formula I used. At first I actually paid 12 bucks for this membership. It tops out though at 4000 followers. Then I used a system I devised myself using BuZZom.com and Tweetspinner.com (I now use this instead... http://tweepi.com much better and faster). Starting on a Tuesday I begin adding new followers. (At first I didn't care who they were, now I am focusing, but that is another story) I slowlyadd followers every day until I max out on Saturday night. I stress... Pace yourself you will get banned for over following. Just add some every day day until you max out. Then on Sunday and Monday I let them ride and wait to see who follows back. Don't forget to follow your "fans" as they are people who are following you because they want to. Always follow back, that is how you create the bond with these people. There are set limits. In the beginning you can only follow so many until you reach 1800, after that it is a ratio of 10% above those who are following you. There is a set limit no matter who you are. Anybody can follow you if they want, there is no limit to that, but we have a limit of those we can each follow. Once you hit that limit don't keep adding more. You may lose your account for that also. Monday evening I start unfollowing those who do not follow me back. I don't care who they are either, if they are not following you back they are basically of no use to you. You want to be on their "timeline" so they see your tweets, if they don't follow you they will not see you. Same rule applies to unfollowing... Do it SLOWLY. Not all at once. Then by say Wednesday night you can start the process over, top out Saturday and let them ride Sunday and Monday. Why Sun and Mon? Sunday is pretty much every persons day off. Monday... People goof off on the computer at work. Monday is a VERY good day on the Internet in general. Keep this discipline up and you will have followers. Then you can get a Worpress plugin (if you use WP) called WP to Twitter. It will post your blog posts whenever a new one comes online. People will click on it, maybe not by the hundreds but a few at a time. They all add up though! One more thing... If you take the time to actually communicate with your followers and re-tweet their tweets you will find out that people will respond in kind and retweet yours. When they do that it means that every follower that they have will see your tweet. Truly a viral format. Takes time and patience. At first I thought it was a waste of time, but now I am convinced otherwise. This guy here has a great Twitter account jokez guy Check his out! Looks like he has a business formula link too, you might want to go see that as well. Looks promising, apparently works well for him. You can see my Twitter account here http://www.twitter.com/yourockradio if you want. Hope that helps!
Thanks! Yeah I have written out about 80 pages I believe everything I know about Twitter including case studies and much more. Hopefully it provides some benefit to some people
I find twitterfollower suitable for this purpose. But the best will be if you do yourself on twitter by finding your desired kind of people. Find them who are grateful to their followers. Who will follow you sooner. Let me know if want more suggestions please. I can work for you if you like.
Twitter traffic tends to be very poor, they come to the site and then they bounce right on off the site again... Personally i stopped marketing on there as it was dragging my bounce rate to well over 80% so i cut their traffic and build more organic SE traffic.
im not sure if you have heard of this method but if you follow the top 10 people on twitter, leave them as friends for 5 minutes, then unfollow them and re-follow them again, your numebr of followers will increase as their followers will see you on the popular person's list and follow you, etc. etc. you could set this on auto via a ghost - might help or just buy one of those twitter adder things and im sure whoever you add would most likely follow you back for obligations - only common people though or something of the sort.
